Checkov错误: AttributeError:类型对象'Lark‘没有属性'_load_from_dict

Question

我在运行checkov时遇到了一些问题，我不熟悉python库，有人能给我一些提示吗？

这在某些机器上工作得很好，但在这台机器上就不行了……

在CentOS中运行：

$ checkov --directory cdk.out

Traceback (most recent call last):
  File "/usr/local/bin/checkov", line 2, in <module>
    from checkov.main import run

    from checkov.terraform.plan_runner import Runner as tf_plan_runner

    from hcl2.parser import hcl2
  File "/usr/local/lib/python3.6/site-packages/hcl2/parser.py", line 53, in <module>
    hcl2 = Lark_StandAlone(transformer=DictTransformer())
  File "/usr/local/lib/python3.6/site-packages/hcl2/lark_parser.py", line 8, in Lark_StandAlone
    return Lark._load_from_dict(DATA, MEMO, **kwargs)
AttributeError: type object 'Lark' has no attribute '_load_from_dict'

在将python从3.6升级到3.8并重新安装checkov之后，它工作得很好。
